Which of the following is true of dehydration?
Explanation
• Dehydration refers to an extracellular fluid volume deficit.
• Dehydration is a common and serious fluid imbalance that leads to hypovolemia.
•
• Fluid loss of 3-5 L of water or 5% of body weight is considered moderate dehydration.
• The thirst mechanism is usually triggered by low blood pressure or fluid volume depletion as small as 0.5%.
• Impaired thirst mechanism can also decrease fluid intake.
• Excessive fluid output without a balancing input can lead to dehydration.
• Dehydration can lead to low tissue perfusion - which is why you may note "skin tenting."
